One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires have
only 1/16 inch (1.6 mm) or
less of tread remaining.

You need a new tire if any of the following statements
are true:
D You can see the indicators at three or more places

around the tire.

D You can see cord or fabric showing through the 

tire’s rubber.

D The tread or sidewall is cracked, cut or snagged deep

enough to show cord or fabric.

D The tire has a bump, bulge or split.
D The tire has a puncture, cut or other damage that

can’t be repaired well because of the size or location
of the damage.
